QDiskInfo, the free open-source S.M.A.R.T. utility, released new 0.4 version in last week!

For those who don’t know about QDiskInfo, it’s a frontend for smartctl to control and monitor SMART (Self-Monitoring, Analysis, and Reporting Technology) Disks, such as SATA and NVMe SSD.

As you see in the screenshot above, it offers the popular Windows app CrystalDiskInfo look like layout, allowing to easily check your disk health, temperature, firmware, total read/write, power on count/time, as well as available spare, critical warning, media errors, etc.

It also supports for saving your disk info in .JSON file, doing self test, and can work in English (C), Greek (el_GR), Spanish (es_ES), Brazilian Portuguese (pt_BR), Simplified Chinese (zh_CN).

And, it supports anime themes. Though, it so far only supports changing theme while building from the source code.

QDiskInfo with theme from Aio edition of CrystalDiskInfo

With the new 0.4 release, the app added official AppImage package for both amd64 and arm64 that works in most Linux Distributions. And, there’s new Disk View dialog for users who have lots of disk drivers to quickly search for a target device.

There are as well many other improvements in QDiskInfo 0.4, including:

• Add option to take screenshot of app window (Save image).
• ASCII view for SATA devices.
• New clear settings options to reset app settings to default.
• New 48×48, 256×256 PNG logo icons.
• Add StartupWMClass to desktop entry to avoid missing app icon on dock.
• Fix NSID issue that make NVMe drives show as bad.
• Fix error on Wayland, and more!

How to Install QDiskInfo

For the official AppImage, just go to Github releases page via the link below:

Expand “Assets” section, and select download either QDiskInfo-x86_64.AppImage for AMD/Intel, or QDiskInfo-aarch64.AppImage for ARM64 (e.g., RasPi) devices.

Then, add executable permission from file properties dialog, and run to launch the app.

NOTE: Ubuntu does NOT support AppImage out-of-the-box since 22.04. Open terminal (Ctrl+Alt+T) and run command to install the libfuse2 library:

sudo apt install libfuse2

For choice, there’s a COPR repository that contains the most recent app package for Fedora 40+ users.

And, for Ubuntu 22.04, Ubuntu 24.04, Ubuntu 24.10 and 25.04, I’ve built the new release package into this unofficial PPA for both amd64 and arm64 platforms.

Just open terminal (Ctrl+Alt+T) and run the commands below one by one to add PPA & install the app:

sudo add-apt-repository ppa:ubuntuhandbook1/qdiskinfo
sudo apt update
sudo apt install qdiskinfo

Note for Aio theme edition (Ubuntu 24.04 only), remove the qdiskinfo package (if installed) and install the package below instead:

sudo apt install qdiskinfo-aio

NOTE: Please inform if any legal issue using the theme images in the package!

Uninstall:

To uninstall the PPA and QdiskInfo package from my PPA, use commands:

sudo add-apt-repository --remove ppa:ubuntuhandbook1/qdiskinfo

sudo apt update

sudo apt remove qdiskinfo qdiskinfo-aio
